Yes, I'll do.

That's odd. I've double checked it by doing a fresh

$ git remote add tip git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip.git
$ git remote update
$ git checkout tip/x86/pat

and applying patches 1-5 in sequence without problems.
(Patches were taken from emails that arrived via my linux-kernel
subscription.) Probably your tip/x86/pat is not at
v2.6.26-rc3-6-g46dd98a?

When trying to apply the patches to tip/master I get rejects for
patches 3 and 5.

Hence I think creating my patches against a feature branch was not a
good idea.

Ok, it's commit 282c454cd3a7041f59a37112bb2f82263bc38f6c which was not
contained in the tip/x86/pat branch. This means I have to adapt patch 5.

Finally a dumb question. What patches do you prefer?
Patches against feature branches (say tip/x86/foo), against tip/master
or against tip/auto-latest as described in your tip.git-Readme?


Thanks,

Andreas
